The Neighbor Discovery Protocol in ipv6 is replaced with which discovery protocol in ipv4?
正解:A
Explanation/Reference: Explanation: Neighbor Discovery -- or ND -- is the protocol used by IPv6 to determine neighboring hosts, and will replace ARP which was used in IPv4. It will perform similar tasks of the Address Resolution Protocol (ARP) and ICMP Router Discovery Protocol. It's purpose remains to get the MAC/Link Layer addresses of available hosts, and the connection information of available routers in the network.
